Abstract
PURPOSE: To simplify a unit which converts coded informatin into a display pattern, by storing display patterns in the excess region of a refresh memory and by reading out a display pattern equivalent to a display information code read out read out previously.
CONSTITUTION: A display information code is set to the lower address of refresh memory 9, and a display pattern is to the upper address. Within periods A and B in the update interval of address counter 7, access to memory 9 is done twice; and then, multiplexer 10 reads out display-code infomrmation in periid B, and elects the display pattern equivalent to te display-code information from fixed-address register 12 in period A before supplying it to memory 9. In period B, a parallel dot pattern code 9 equivalent to the scanning line indicated by horizontal countr 8 among corresponding display patterns is read out from memory 9 and supplied to video amplifier 5 via parallel-series converter register 4, thereby displaying it on display part 6.
